After the gory attack, the footage showed the attacker cleaning the machette of blood with the woman's napkin, taking away her phone and leaving the kiosk after pulling down the rolling shutter, police said.
 
The woman was lying in pool of blood for a long time and the incident came to light when two school children raised an alarm seeing blood coming out the kiosk from under the shutters, police said.
 
She was taken to Victoria Hospital by a traffic policeman and later shifted to BGS Global Hospital.

Bangalore police has set up several squads to nab the assailant based on the CCTV footage.
